Mark Moxon has been porting the original (BBC Micro) version of Elite to a teletext-style output, using the Beeb’s Mode 7, which uses a teletext chip for display.
Up to now the output - mostly vector graphics - have been in monochrome, but now:
I’ve been busy adding colour to the trading screens in Teletext Elite, as an homage to Ceefax and Oracle. Ah, this brings back some happy memories! Still on-track for a release this weekend
The codebase is literally BBC Micro disc Elite, just with teletext graphics routines replacing the pixel routines. So this is the real deal… just in teletext.
Here’s a still from a very short movie:
It’s possibly a little quicker, but not by much. The underlying maths is exactly the same, I’m just scaling the results for teletext and using sixel-plotting routines rather than pixel plotting. As the maths is probably the slow part, switching to teletext doesn’t speed things up much.
The exception is the sun, which works on a raster line system, so with only a quarter of the raster lines, things don’t slow down as much when you go sun-surfing.
